The primary function of a splice closure in fiber-optic installations is to protect optical fibers and splices from environmental changes. Splice closures are designed to create a secure and weatherproof environment for the optical fibers, which are inherently vulnerable to moisture, dust, and temperature variations. By ensuring that the splices are sealed and protected, these closures help maintain the integrity and performance of the fiber-optic network, preventing signal loss or damage that could arise from exposure to environmental factors. This protective feature is essential for ensuring a long-lasting and reliable connection in various deployment environments, whether they are underground or above ground.

The other options, while they may be related to fiber-optic systems, do not accurately reflect the primary function of a splice closure. Enhancing signal strength, increasing flexibility, or enabling easier access to the fiber during maintenance are not the main roles of a splice closure, which is focused primarily on safeguarding the splices from external influences.
